So another trip and more faith in good people everywhere. Whether it's in the jungles of Costa Rica, or Bourbon Street, or Jamaica, (well, perhaps not Bourbon Street ), you meet so many good people.

There is a quote that the less you travel, the more certain you are that you're right. That's a generalisation, obviously, but I think there's a measure of truth in it.

Its a complicated world. I saw wonderful acts of kindness and I listened to Texas redneck radio saying the Sandy Hook school killings didn't happen and were a Government conspiracy designed to make gun owners look bad!

Then you go to San Antonio and see a lovely city in festive mood, you see the Alamo, take a photo of the plaque showing the names of the defenders, including David Crockett and Jim Bowie. Before that you look down from the Texas Depository building in Dallas and get surprised at just how close the grassy knoll is to where the President was shot.

By now, you understand the American culture much better. You don't necessarily agree with much of it and you hand out tips constantly, but you embrace it.

You walk into a shop in New Orleans to buy a luggage lock and leave with a super-duper lightweight small pair of binoculars for the footy and love the interaction.

You go by fast boat for two hours to an isolated village in the jungles and rivers of Costa Rica, on the Nicaragua border and walk along a jungle track (for tourists, of course) and get told to be careful of the fer-de-lance snake a few feet in front of you.

You go on an open boat and watch monkeys swinging from one tree to the next, watch sloths in the trees, iguanas and alligators.

You get very familiar with the undesirable aspects of Costa Rica belly.

After the heat of the jungle, you appreciate the air-conditioning of the Serenade of the Seas, you 'yeah, man' everyone in Jamaica, hold turtles in Grand Cayman and see a tiny bit of Mexico.

You drive from San Antonio to Dallas Fort Worth Airport, get lost and panic that you'll miss your flight.

You put on Facebook that you're a bit tired after a 16 hour flight, and then read the advice that you need to 'toughen up, princess'.
